Step-by-step explanation:
Bacon's Rebellion in 1676 was primarily caused by a combination of economic inequality and political unrest. The smaller planters and landless tenants in Virginia were resentful of Governor Berkeley's favoritism towards the wealthiest residents, who received the best land and paid low taxes. The declining price of tobacco, due to trade restrictions and war, made it harder for the colonists to afford the high taxes, exacerbating their grievances.
